why is only "win" and "mac" supported? what is preventing us from enabling it
for other platforms?

[Sharu Jiang, 2016/09/20 18:02:57]

This comment is an example of what cracas config looks like, it's not exactly
the same as in config page. In config page, we will support:
    "canary": [
      "win",
      "mac",
      "android",
      "linux"
    ]

After some testing, we will enable other channels as well.

nit: make it clear that it is an example of the config.
Sorry for my bad sample above.

Done.
